The Three Bodies was a Chinese story about the war and confrontation between the Earth civilization and the Three Bodies civilization. The final ending of the novel did not clearly state what the end of mankind would be like, but it could be speculated that mankind might face a huge disaster and destruction. In the novel, the Three-Body Civilization had powerful technology and military strength. They invaded Earth and destroyed human civilization and technology, making it impossible for humans to resist. Although humans had paid a huge price in the war, there were still some humans who survived and re-established a new civilization. As for where these humans went, we can't be sure. The novel did not specify whether they survived or returned to their original planet. They may have established a new civilization in a new galaxy or continue to search for life and civilization in a new universe.
